PAVE‑SEAL NW40‑SS‑150‑4P‑KT30‑5T‑26BEAD — 

---

Attribute	Value / Notes
Product family	PAVE‑Seals hermetic feedthrough (electrical/fiber optic).
Flange / port	NW40 (KF40) vacuum flange interface (fits NW40/KF40 style hardware).
Housing material	SS → Stainless steel (as indicated by “SS” in part number).
Connector / pin count	4P → likely 4‑pin electrical feedthrough (interpreted from part string).
Thermocouple / sensor option	KT30 → likely indicates K‑type thermocouple option or K‑type termination with 30 mm lead/length (inferred; see note).
Number of thermocouples / terminations	5T
Wire / bead size	26BEAD → likely 26 AWG bead‑style thermocouple/wire (inferred).
Hermeticity / leak rate	Helium leak test typical acceptance: ≤ (1\times10^{-6}) cc/sec (example from PAVE drawing notes).
Dielectric / hipot	Typical hipot: 630 VDC; insulation resistance ≥ 500 MΩ (example test values from drawing notes).
Wire exit / orientation	Wires exit through the seal; exit position is approximate/variable per drawing notes.
Typical applications	Vacuum or pressure environments requiring hermetic electrical or thermocouple feedthroughs.

How the part number is interpreted (inferred)

• NW40 — indicates the flange/port standard (NW/KF‑40).
• SS — stainless steel housing.
• 150 — may reference a specific flange/clamp style or internal PAVE drawing number (not uniquely resolvable from public docs).
• 4P — 4‑pin electrical feedthrough.
• KT30 / 5T / 26BEAD — likely denote thermocouple type (K), lead/termination style/length, quantity of thermocouples/terminals, and wire gauge/bead style; these are reasonable interpretations based on PAVE naming conventions but are inferences and should be validated with the factory.

Note: several items above are inferred from PAVE product literature and a representative drawing; the exact meaning of numeric codes (e.g., “150”, “KT30”, “5T”, “26BEAD”) is product‑line specific and not fully documented in the public snippets located. When making inferences I relied on PAVE’s design guide and a representative drawing that lists test criteria and wire/termination notes.

Key test / acceptance criteria (from representative PAVE drawing)

• Helium leak test: ≤ (1\times10^{-6}) cc/sec.
• Hypot: 630 VDC typical.
• Insulation resistance: ≥ 500 MΩ typical.
